Balance the following chemical equations:

If 90.0 grams of ethane reacted with excess chlorine,how many grams of dicarbon hexachloride would form

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.

Technician a says that you should never jump-start a frozen battery. technician b says that a frozen battery can explode, causing injury, when jump-started. who is correct?
